Can I fit an LS7 into my 73?
I could not find any threads about it.
No issues drops right in .Only issues is where you want your dry sump tank .
Can it be wet sump?
Like a ls3 oil pan?
Got a chance for a 5000 eng trans.
Yeah...space is limited and the parts are expensive. If I had to do it again....I would convert it to a wet sump.
My car is a 1970
Maybe I will stick with LS3, I wanted instead.
Bet it is a hoot to drive though.
LS3 is a great engine....but its not an LS7. There’s just something about 427 cubes!
You can’t compare the two cube for cube. The LS7 is 60+ ci bigger! That’s significant. Just saying lol..
As much charm as the LS7 has, I'd probably go LS3. The LS7 had some pretty serious cylinder head issues. Unless you get one that's already had the valve guides replaced, it's a problem waiting to happen.
Yes, depending on production date, my understanding is as of February 2011 GM had isolated the valve guide issue.
Not really...the LS9 also had some bad heads but it’s not a epidemic like the internet makes you believe. Not every corvette owner hangs out on the corvette forum. It cost me nothing to have the heads checked and there was nothing wrong with them at 38k miles. If the heads were defective, they failed early in life.
Yes 427 has a very nice ring to it when asked your engine size...
Seems just like old days where BBC parts were more $ than SBC.
What is the 396 version in LS series?
LS3 may be more forgiving if a turbo or two were needing space.
